I have the same problem. I bought a ThinkPad T14 gen 5 in May this year. Worked perfectly with Noble, but now, after the evil Oracular Oriole has eaten the nice cute Numbats, I got the ghost screen as described in this bug report. This is very disturbing, starting from the mouse pointer not stopping at the right border of the screen as there is the ghost desktop where it enters, also having windows extending into that area or even completely getting lost there. And when I wanted to give a talk on a conference 3 weeks ago I had major difficulties with the projector, especially I cannot switch the "Mirror" mode, probably due to having 3 and not only 2 screens. I need "Mirror" to see my slides on my laptop on the podium while they are also on the projection screen, so that I do not need to look behind me all the time.
